WetGeek I'm thinking it could be 5, 10, 15, 20, 25, 30 ... assuming no dual boots.
Right. Because 20% is one fifth of 100%, a number divisible by 5 that results in a whole number. 5/5=1, 10/5=2, 15/5=3 and so on.
WetGeek How many do you suppose Tom can afford?
You have to factor in the question "How many do you suppose Tom can get away with before being murdered by his husband?"
I'm pushing it at 5 right now (well, 6 if you count the Optiplex 7050 Micro that I keep in a drawer and bring out from time to time to build "portable M.2" drives, but the 7050 doesn't have an installed OS, so it might not count). I'm guessing that I could go as high as 7-8 before the threats of murder started rumbling too loudly. Take heed. You are at 7 already. 🤣
